Explanation:
A basic law of magnetism is that unlike poles attract each other. Two bar magnets can illustrate this. One is hung so that it swings freely. A pole of the second is brought, in turn, near each of the two ends of the hanging magnet.
Answer:
d
Explanation:
good question. now the bus is moving in constant velocity . a student in front tosses a ball to the student in back. but we dont know the speed at which the student tosses a ball. we have to assume the speed
assume the speed of ball is slightly less than the speed of bus. in this case the stationary observer sees the ball in slower speed than the one inside the bus.
so a is correct
now assume the speed of ball is 1/2 the speed of bus. here stationary observer sees the ball the same speed as the one in bus observe
b is correct
assume the speed of ball is very small than the speed of bus . in this case the stationary observer see in grater speed than the student in bus
e also correct
so correct answer is d. it depends on the speed of ball tossed by the student in front.
Answer:
Vitamin A
Explanation:
I'm guessing though so double check.
It could also be an iron deficiency.
Answer:
v=10.78 m/s
Explanation:
Given that,
The student estimates that the apple traveled 1.1 seconds straight down to the ground. We need to find the maximum velocity of the apple before it hit the ground. The initial velocity of the apple is equal to 0 as it was at rest. It will move under the action of gravity.
Using equation of motion to find it as follows :
v=u+at
a = g
⇒v=gt
v=(9.8 m/s²) × (1.1 s)
v = 10.78 m/s
So, the maximum velocity of the apple is 10.78 m/s.
Answer:
<h3>The answer is 61,200 m</h3>
Explanation:
To find the distance covered by the dolphin , we use the formula
<h3>distance = velocity × time</h3>
From the question
velocity = 17 m/s
time = 3600 s
We have
distance = 17 × 3600
We have the final answer as
<h3>61,200 m</h3>
Hope this helps you
